I dislike having to do this, but Clang sees them as unused and removes them
from the object file, causing linking to fail.
The real solution here is to remove all the assembly code because it's 2016
and this game doesn't have to run on 133MHz Pentium now. :)
This was a _ton_ of changes, made 15 years ago, so there are probably some
problems to work out still.
Among others: Engine/Base/Stream.* was mostly abandoned and will need to be
re-ported.
Still, this is a pretty good start, and probably holds a world record for
lines of changes or something. :)
